Platinum Temperature Sensors

Instruction Sheet

Please carefully read this instruction thoroughly prior to use the DVP04PT-H.

In order to prevent electric shock, do not touch the terminals or conduct any maintenance while

power to the PLC is ON.

Do NOT open the PLC. Only qualified personel or Delta staff is allowed

to conduct any internal electrical work on the PLC.

This is an OPEN-TYPE device, and was certified to meet the IEC 61131-2 (UL 508) safety

requirements when installed in an enclosure.

The DVP04PT-H must be kept under the environment away from high temperatures, high

humidity, exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles.

Do not apply AC power to any of the input/output terminals, or it may damage the DVP04PT-H.

Make sure that the DVP04PT-H is properly grounded , to prevent any electromagnetic noise.

Use wires with resistance when connect the platinum resistance thermister (RTD) to PLC.

Please keep the wires as short as possible when connecting the RTD to PLC, and keep power

wires as far away as possible from I/O wires to prevent noise interference.

2 INTRODUCTION

2.1 Model Explanation and Peripherals

 Thank you for choosing DELTA DVP PLC Series. DVP04PT-H allows the connection of four

platinum temperature sensors (PT100 3-WIRE 100 Ω 3850 PPM/°C (DIN 43760 JIS

C1604-1989)). The DVP-PLC EH MPU converts the sensors input into a 14 bit digital signal, and

then be manipulated by using TO and FROM instructions in the ladder logic program. There are

49 Controlled Registers (CR, each register has 16 bits) in each module.

 Software version DVP04PT-H platinum temperature sensors can be updated via RS-485

communication.

 DVP04PT-H displays both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1

degrees and for Fahrenheit is 0.18 degrees.

1. Upon power-up, the ERROR LED will light on for 0.5 seconds the POWER LED will light on continuously.

2. POWER LED on and ERROR LED off means No Error.

Low Voltage error (lower than 19.5V), ERROR LED will blink continuously till the power supply goes above 19.5V.

3. DVP04PT-H is connected to PLC MPU in series = RUN LED on MPU will be lit and A/D LED or D/A LED should blink.

4. After receiving the first RS-485 instruction the A/D LED or D/A LED will blink.

5. If the input or output exceeds the upper or lower bounds, then the ERROR LED will blink.
